Can't boot since 2.4.21-rc2-ac3 with dvb-kernel

Can't boot since 2.4.21-rc2-ac3 with dvb-kernel

[Gregoire Favre]

Hello,

with 2.4.21-rc2-ac2 I can boot with dvb-kernel (I have recompiled with
latest CVS from dvb-kernel without problem). But since 2.4.21-rc2-ac3 I
don't manage, for example with 2.4.21-rc6-ac1, I got:

ksymoops -v /usr/src/linux-2.4.21-rc6-ac1/vmlinux -K -L -l /lib/modules/2.4.21-rc6-ac1/ -m /usr/src/linux-2.4.21-rc6-ac1/System.map 2.4.21-rc6-ac1-err

Without dvb-kernel, the system boot perfectly...
I lauch the dvb at boot with initscript like:

/usr/src/CVS/dvb-kernel/driver.av7110 start

Should I provide some other infos?

Is there anything I could do to make it works?

Hello Gregoire,

> as already repported with older ac and older CVS of dvb-kernel, same
> Oops with 2.4.21-rc7-ac1:

Are you sure you have used the v4l2 "videodev.o" (backported from 2.5) 
that comes from the "build-2.4" directory from the "dvb-kernel" cvs tree?

 > Trace; fab4a2bb <[videodev]video_open+182/1d2>

This looks suspicious...

Please do a
 > find /lib/modules/ -iname "*videodev*"

If you have a "videodev.o" in .../kernel/drivs/media/video, then this 
will be used. But this is the plain old 2.4 video4linux-*1* videodev 
module, which does not work in conjunction with the "dvb-kernel" CVS 
driver, which needs the 2.5 video4linux-*2* videodev.

Please don't CC the linux kernel mailing list the next time, since this 
is a dvd only issue. Thanks!

CU
Michael.

Argh!!!

I completely forgot this!!!

Well, I have rebooted now under 2.4.21-rc7-ac1 and it works just
great!!!

I completely agree with this, unfirtunately, as I completely forgot to
remove the kernel/drivers/media/video/videodev.o to kernels newer than
2.4.21-rc2-ac2 and as the compilation of new dvb-kernel worked perfectly
for 2.4.21-rc2-ac2 I thought it was due to a change in the kernel...

Sorry for the posts!!! But thank you very much,
